If the application is configured to use the legacy RESTful action mapper, a crafted request can inject an OGNL expression that may lead to remote code execution. Struts 7 is affected only when the OGNL allowlist is disabled; it is enabled by default. Applications using the default action mapper, the restful2 mapper, or the Struts REST plugin are not affected.\n\nThis issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0.\n\nUsers are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.","state":0,"publishedAt":"2026-10-05T18:35:10.026+00:00","modifiedAt":"2026-10-06T14:09:06.711+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.struts:struts2-core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Struts\",\n                    \"packageURL\": \"pkg:maven/org.apache.struts/struts2-core\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.0.0\",\n                            \"lessThanOrEqual\": \"2.3.37\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.5.0\",\n                            \"lessThanOrEqual\": \"2.5.33\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6.0.0\",\n                            \"lessThanOrEqual\": \"6.11.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.0.0\",\n                            \"lessThanOrEqual\": \"7.3.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.struts:struts2-core\"\n                }"}],"metrics":[],"references":["https://cwiki.apache.org/confluence/display/WW/S2-075"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104711","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104711","identifiers":["CVE-2026-104711"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
